[MiniProject] Convert Vietnamese unicode strings to unaccented strings

Recently, I embarked on an exciting Arduino project where I needed to convert Vietnamese Unicode strings into their unaccented equivalents. The goal was simple, but I quickly ran into a problem: the conversion process wasn’t working as expected. Characters like "Độc lập tự do" were returning as a string of question marks!

I reached out for help and discovered that the issue was rooted in the way UTF-8 encoding was handled in my code. With some guidance, I learned how to properly decode UTF-8 characters into their Unicode equivalents before converting them. By breaking down the string into manageable arrays and thoroughly testing each case, I finally got the correct output: "Doc lap tu do."

This project taught me the importance of understanding encoding and the value of community support in problem-solving. Now, my Arduino project runs smoothly, converting Vietnamese text as intended!

The serial Monitor output:

Note:
This project comes easy if you have already had some experience with Arduino, LCD 16x2 shield, C/C++ programming, Unicode encoding, testing techniques, and AI literacy. If you don't know those things, don't be afraid, just google it or contact me. I am happy to help you with one week's feedback.

[Git] Handle trailing space when patching with git

After complete coding one module in development branch. Next phase is merging. Obviously, you can merge source code automatically without no errors happen. However, life is not dream. Create a patch git diff HEAD > newTariff.patch Apply patch git apply newTariff.patch then problem happens Problem git apply newTariff.patch:106: trailing whitespace. patch does not apply Route cause: Nguyên nhân: Do trong source code có những dấu space thừa (ô vuông màu đỏ hình dưới) Some whitespaces is existed in your patch. (red area in below pictures) Fix Clean white space and patch again. Cách khắc phục Xóa những dấu space này đi và thực hiện patch lại Make up after complete coding. Find and clean whitespace before create patch file. Sửa sau khi code xong Kiểm tra sau khi code xong có lỗi này không git diff HEAD --check Prevent whitespace by manually when typing source code Sửa ngay khi đang code =>Bật chức năng hiển thị các dấu whitespace, hoặc remove trailing
